IP ranges are the different blocks of IP addresses advertised by an Autonomous System (AS). These ranges can be used by the same organization operating the AS, or by different organizations.

Peers of AS23138

16 peers

AS1828 AS3701 AS6939 AS18106 AS293 AS4181 AS7575 AS9002 AS34927 AS137409 AS394256 AS24482 AS35280 AS49544 AS53828 AS58511

AS23138 peers with these other Autonomous Systems.

Peering is a direct, often free, traffic exchange between Autonomous Systems (ASNs). They share routes only to their own networks and customers, making connections faster and cheaper for that specific traffic, without providing full internet access to each other.

Upstreams of AS23138

2 upstreams

AS16713 AS20055

AS23138 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS23138 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS23138

3 downstreams

AS4539 AS13752 AS21615

AS23138 provides internet connectivity to these downstream Autonomous Systems.

A downstream is a customer Autonomous System that pays another AS (its provider) for internet access. The provider AS carries the downstream's traffic and makes its network reachable.
